Abstract

Nowadays, GNSS receivers have scores – and often more than one hundred – of channels, enabling them to track GPS, Glonass, Galileo and Compass signals simultaneously. The whole workfl ow from satellite tracking to calculating the coordinates of the position in a preferred reference system can be conducted automatically in real time. The price of GNSS receivers has dropped steadily since the fi rst GPS receivers came onto the commercial market in 1982. In conjunction with the latest product survey results for GNSS receivers (available at www.geomatching. com), the author puts today’s GNSS status and features in perspective
